Answer:
Ionic compounds have a metal and nonmetal.
Ionic compounds are made up of ions.
Explanation:
You did not provide any formulas for me to correct, but:
- ionic compounds tend to have metals and nonmetals. (EX: NaCl)You can look at the periodic table to see which elements are metals and which are not.
- ionic compounds are made up of ions. Ions are elements that have a charge (Like
or
). To have a correct ionic compound, make sure that the ions inside of it "cancel" each other out.
EX: Na has a +1 charge. Cl has a -1 charge. When they are paired up, they successfully cancel each other out (become neutral) and become the ionic compound NaCl.
The chart below shows you the charge of each element. Make sure the charge of the elements in an ionic compound "cancel" each other out.
The very last chart shows the metals and nonmetals

Answer:
If you continue to cool water past 4 degrees Celsius, its density starts to plummet (you can see this in the graph). At zero degrees, i.e., the temperature at which water turns into ice, the density of water is actually quite low. It turns out that ice has a lower density than water, and any object that has a lower density than the liquid form on which it’s kept (in this case, water) will be able to float!
Explanation:
Answer:
A.) A cinder cone vocano
Explanation:
Cinder cone volcanos give off more ash, rather then an explosion, hense the name "cinder cone".
Answer: Ok so the MOLE (mol) is a unit of measurement representing the amount of a substance that contains the same number of atoms as there are molecules in exactly 12 grams of carbon-12 (i.e., 6022X1023).
Explanation: And that's how it goes, I hope you understood it well!
